Using Multiple Input Multiple Output as Hybrid Free Space Optics/Radio Frequency Links
نویسنده
چکیده
This paper describes overview and definitions about Multiple Input Multiple Output (MIMO) formats which can be used in hybrid Free Space Optics/Radio Frequency (FSO/RF) links. Free space optical links allow obtain high speed data transmission without optical fibers. This type of communication is dependent on weather properties and line of sight is needed. This fact has negative influence on infrared beams which are being use for transmission. Radio frequency links have different restrictions in compare with FSO links. Both links can complement each other. Availability can increase with using hybrid FSO/RF links as MIMO systems. Keywords—free space optics; hybrid FSO/RF links; radio frequency links; MIMO systems

BER Analysis of BPSK-SIM based SISO and MIMO FSO systems in strong turbulence with pointing errors
Free Space Optics (FSO) is one of the sprouting technologies in optical communication systems domain. It can be employed as an alternative for the conventional radio frequency (RF) links to work out the current limitations in communication systems. But, the major drawback in FSO communication is the effect of random environment conditions on its performance. In this paper, we analyze the bit er...
متن کاملHybrid Free-space Optics/radio Frequency (fso/rf) Networks for Mobile Robot Teams
In this paper, we introduce a hybrid free-space optics/radio frequency (FSO/RF) networking paradigm for mobile robot teams. We believe that such a model will emerge as a consequence of inherent limitations of RF based approaches. FSO technology has the potential to provide tremendous increases in per-node throughput for a mobile ad-hoc network (MANET). To motivate this paradigm, we first provid...

The HSDPA (High Speed Downlink Packet Access) mode of UMTS provides high data rates to the user. In this contribution comparisons, based on free space measurements, between SISO (Single Input Single Output) HSDPA and MIMO (Multiple Input Multiple Output) HSDPA are shown. For two transmit antennas the STTD (Space-Time Transmit Diversity) mode of UMTS is used to increase the diversity order of th...

Free-space optical (FSO) communication is a cost effective and high data rate access technique, which has been proving itself a best alternative to radio frequency technology. FSO link provides high bandwidth solution to the last mile access bottleneck. However, for terrestrial communication systems, the performance of these links is severely degraded from atmospheric loss mainly due to fog, ra...

A Multiple Input, Multiple Output (MIMO) diffuse optical communications link is implemented and evaluated in this letter. We have adapted a 2x2 Alamouti-type space-time coding (STC) scheme to increase link performance beyond that of Single Input, Single Output (SISO), and Multiple Input, Single Output (MISO) systems. Using our experimental testbed and indoor field measurements, we present a rep...
